SLIDING SHELF FOR COOK-STOVES.

SPECIFICATION forming part of Letters Patent No. 358,361, dated February22, 1887.

Serial No. 199,659. (NomodcL) To all whom it may concern:

Be it known that I, MATTHEW KUEHNLE, of the city of St. Louis, in theState of Missouri, have invented a certain new and useful Improvement inAutomatic Sliding Shelves for Cook-Stoves, of which the following is afull, clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification, in whichFigure l is a horizontal section of the oven portion of a cooking-stove,showing the shelf and door entirely closed. Fig. 2 is a horizontalsection, showing the door partly opened,

the vertical upwardly-extending stud on the end of an inwardly-curvedoperating-arm having just come into contact with thedownwardly-projecting front rail, along the inner side of which it runs.Fig. 3 is a detail horizontalsection, showing the door further openedand the shelf partly withdrawn in full lines, and the door opened to itsfull extent and the shelf two-thirds withdrawn in broken lines. Fig. 4is a detail horizontal section, showing the door and arm on theirreturn, which have moved the shelf inward to the position shown in fulllines in Fig. 3. Fig. 5 is a perspective view of a stove embodying myinvention, showing the shelf partly removed from its normal position;and Fig. 6 is a detail enlarged perspective view of a part of the underside of the shelf, showing the depending trackrails, on the sides ofwhich the stud of the op erating-armworks. Fig. 7 is ahorizontal sectionof the means for connecting the arm to the door, the parts beingseparated.

My invention relates to certain improvements in automatic slidingshelves for cookstoves, and is an improvement on my invention embodiedin the application filed by me under the same title on the 17th day ofNovember, 1885, Serial No. 177,030.

The invention consists in features of novelty hereinafter fullydescribed, and pointed out in the claims.

My invention provides an easy automatic means of withdrawing theoven-shelf simultaneously and in conjunction With the opening of thedoor for the inspection of the roast, &c.

Referring to the drawings, similar letters of reference represent likeparts in all the figures.

A rep resents an ordinary cook-stove, and B one of the ovendoors to thesame.

0 is an arm or lever curved inwardly at its inner portiomwhose lip G issecured to a projection, B, between angle-brackets B on the door. (SeeFigs. 1, 2, 3, 4, and 7.) The-lip of the arm is seated within theangle-brackets of the projection on the door, and is secured thereto bya bolt, 0", and its nut C, said bolt passing through the lip of the arm.The inner end of the arm is provided with a vertical upwardly-extendingstud, Ofiwhich, as the door opens or closes, is moved (part of the waywith an eccentric movement) along the sides of projecting front and reartrack-rails, D and D, respectively, the said rails being secured belowthe bars of the sliding shelf E, so as to depend from the latter. Anangle side arm, D from the rail D extends rearward beneath the bars ofthe shelf, and at its terminal is provided with a dog-stud, D thatprevents the accidental entire withdrawal of the shelf. The movement ofthe arm is so arranged as to bring the bearing force of the Verticalstud nearly on a line with the movement of the shelf, and thereby toproduce a minimum of lateral force and friction. The shelf slides onsupporting ledges or brackets F,secured to the side plates of the oven.Guides or keepers G, attached to the side plates above the shelf, steadyits movement and prevent its tilting. The shelf is strengthened byvertical ribs E on the top at its sides, which slide in vertical groovesG in the guides or keepers, and are necessary to brace it whenwithdrawn, especially when heavily loaded and slid out to its utmostcapacity. It will be seen that the front and rear rails are parallelwith the shelf-bars, and the angle side arm transverse of the latter.The rear rail, D, has an inwardly-curved end, D*.

The operation of my device is as follows:

The door has liberty to open sufficiently for a slight inspection of thecontents of the oven (see Fig. 2) without removing the shelf. The studof the operating-arm then comes in con tact with the track-rail D at C,Fig. 2, and, as the door opens, after a slight eccentric motion in theopposite direction, slides along that rail until it is cornered at itsangle-bar at 0 (see Fig. 3,) when the shelf will be about twothirdswithdrawn from the oven, which is its limit of withdrawal. W'henclosing, the stud comes in contact with the curved end of the shorttraclerail D at C, (see Fig. 4,) and commences an eccentric movementthereon, passing nearly to the far end of said track, when it begins toretrace its course until, when the shelf is closed, it leaves the trackat its curved end and, as the door closes, attains the position shown inFig. 1.

In Fig. 5 I show the angle brackets B formed on the arm, and heldbetween flanges B on the projection by means of a washer, C", and abelt.

I prefer to cast the lip of the operating-arm with a slotted way, asshown in Fig. 7, which provides a passage between projections C' for thebolt that secures the arm to the door, and saves the labor of drilling.

Although I prefer the form and position of the curved arm andtrack-rails as shown, I do not confine myself thereto, as it is evidentthere might be changes in both form and position of the same withoutdeparting from the essential features of my invention.

I claim as my invention 1. A shelf, E, formed with downwardlyprojectingfront track-rail, D, rearwardly'extending side arm, D, having dog-studD, and rear track-rail, D, parallel with the front track, havinginwardly-curved end D, substantially as described.

2. A shelf, E, formed with front track-rail, D, angle side arm, D havingdogstud D, rear track-rail, D, having inwardly-curved end D, and thevertical ribs E, substantially as described.

3. The combination of a shelf, E, formed with a front track-rail, D,angle side arm, D, and rear track-rail, and the operating-arm O, curvedinwardly at its inner portion and provided with a verticalupwardly-extending stud, O, substantially as described.

4. The combination, with a cooking-stove, of a sliding shelf formed witha track-rail, D, having an angle-arm, D, provided with a stud, D and anarm, 0, having a vertical stud, 0 hearing on said track-rail, substantially as shown and described.

5. The combination of the door havinga projection, B, the arm 0, formedwith a lip, 0 the angle-brackets B" B, and a bolt, G, and nut 0 by whichthe lip is secured to the projection, substantially as shown anddescribed.

6. The combination of the door formed with a projection, B, andangle-brackets B 13 the arm 0, formed with a lip, O", and a bolt, 0, andnut O, by which the lip is secured to the projection, substantially asshown and described.
